Answer:
She needs to run 21 more minutes.
Step-by-step explanation:
2 blocks = 1 minute
18 blocks = 9 minutes
60 blocks = 30 minutes
She already ran for 9 minutes. She needs to run 42 more blocks.
If we subtract 9 minutes from 30 minutes, we get 21 minutes. Therefore, she needs to run 21 more minutes.
The area and the amount of gravel are illustrations of proportions.
7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
The given parameters are:

The number of pound for an area of <em>1 square foot </em>is calculated as follows:

So, we have:


Cross multiply

Divide both sides by 36

The area to be covered with 315lb gravel is calculated as follows:

So, we have:


Cross multiply


Divide both sides by 252

Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
